Title: Package serving for display
Inventor: ISOBE MOTOO
IPC: B65D5/52
Filed: 1993-09-21
Abstract: PURPOSE:To economically and easily tile a package containing stick-like products to allow a customer to easily recognize the products and also to allow the products to be easily taken out. CONSTITUTION:A bottom 11a of a package 11 containing sticklike products 14 is cut to stand, and leg 13 is formed on a rear part of the bottom 11a. When the package 11 is mounted on a show case 15, the leg 13 causes the package 11 to tilt so that the products 14 can easily be recognized and the products 14 can easily be taken out. In addition, since the leg 13 is formed by cutting a part of the bottom 11a, the package 11 can easily be assembled and is also economical with minimized material cost.

IPC: C02F11/14
Filed: 1987-10-13
Abstract: PURPOSE:To deodorize sludge without degrading the flocculating function of a cationic high-polymer flocculating agent to the sludge and to efficiently carry out a dehydration operation without degrading environment by adding slaked lime to the gravity-dehydrated sludge to deodorize the sludge prior to force dehydration. CONSTITUTION:The sludge generated by various water treatments of night soil, city sewage and industrial waste water is flocculated to large flocs by addition of the cationic high-polymer flocculating agent thereto. The water liberated among the flocs by gravity dehydration is efficiently removed in a large volume. The slaked lime is added to such gravity-dehydrated sludge prior to the force dehydration, by which the sludge is efficiently deodorized in the state of decreasing the amt. of the slaked lime to be dissolved in filtrate.

Title: Solenoid
Inventor: ITAKURA KAZUHARU
IPC: H01F7/16
Filed: 1986-10-29
Abstract: PURPOSE:To make a low noise and to strengthen holding force after attraction by providing a small hole at the bottom of a cylinder which attracts a movable part to control the flow of air. CONSTITUTION:An air hole 4 is provided for controlling the flow of air at the bottom of a cylinder 2 wherein a movable part is attracted. When a current flows in a coil 1, a plunger 3 is attracted in the cylinder 2. In this case, the air in the cylinder 2 is gradually exhausted from the air hole 4 since the leakage of the air from the gap between the cylinder 2 and the plunger 3 is minimized by providing a piston ring 5 at the entrance of the cylinder 2. This makes the pressure of the air in the cylinder 2 higher, the plunger 3 is attracted in the cylinder 2 at a low speed and the shock noise when the plunger 3 hits the bottom of the cylinder 2 is made small. The bottom of the plunger 3 is also brought into contact with the bottom of the cylinder 2 directly and fixed and the holding force after the plunger 3 is attracted in the cylinder 2 is made stronger.

Title: Electric discharge machining device
Inventor: TAKAHASHI TOSHIAKI
IPC: B23H1/02
Filed: 1987-10-15
Abstract: PURPOSE:To independently set each voltage value of a resistance control switch circuit and a resistance-free switch circuit from one dc voltage source by obtaining the dc voltage source of the resistance control switch circuit through the voltage lowering from the dc voltage source of the resistance-free switch circuit by a dc voltage converter. CONSTITUTION:When a switch 9 is turned ON, a discharge current IR flows in a resistance limit switch circuit consisting of a counter current suppressing diode 10 and an electric current limit resistor 11 by the charged voltage of a condenser 13 as dc voltage source. When a switch 5 is turned ON, an electric current IL flows in a resistance-free switch circuit consisting of a counter current suppressing diode 6, and is superposed to IR, and the switch 9 is turned OFF immediately after said superposition, and then the switch 5 is turned OFF after a prescribed time. In this case, the dc voltage source of the resistance limit switch circuit due to a condenser 13 generates the voltage of the dc voltage source 4 of the resistance-free switch circuit through the voltage reduction by a dc voltage converter 14. Thus, each voltage value of the resistance-free switch circuit and the resistance control switch circuit can be obtained independently from one dc voltage source.

Abstract: PURPOSE:To roll a tube without generating excess shearing strain in a shell by inclining the roll axis of a conical roll of a two roll type skew rolling mill at a prescribed angle to the pass center, crossing and approximately fixing the difference between the circumferential speeds of the roll and shell. CONSTITUTION:In the two roll type skew rolling mill in which a mandrel bar 3 is used for an internal tool, the roll axis of the conical roll 1 of which the roll diameter is monotonically reduced from the inlet side to the outlet side is inclined to the pass center in a vertical plane at the prescribed angle theta and crossed, the difference between the circumferential speeds of the roll and shell 2 at each position is approximately fixed and forces in the circumferential and axial directions are applied. So, the generation of excess shearing strain in the shell 2 is prevented and the running out property is improved. Thus, limit wall thickness/outside diameter can be reduced and manufacturing range can be expanded.

Title: Toner image fixing device
Inventor: INUKAI KATSUMI
IPC: G03G15/20
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a toner image fixing device capable of excellently preventing the flicker from occurring at the standby time. SOLUTION: This device is constituted to make a current (B) to a heater turned on, during the time when the temp. (A) of the heater for fixation rises from ta to tb, at the image forming time. When the temp. reaches tb, the current to the heater is turned off until the temp. falls to ta. Then, assuming that it is switched from the image forming mode to the standby mode at the time to, the temp. (A) of the heater for fixing is controlled to change over a range from ta' to tb' which is lower and wider than that of the range from ta to tb. Thus, the frequency of on-off switching of the current (B) for the heater at the standby time is remarkably reduced as compared with that at the image forming time.  Then, the interval of on-off switching of the lamp current (C) to energize the heater for fixing is made longer, while the interval for on-off switching and generating the rush current is made longer, therefore the change of the power source voltage of a lighting equipment due to the rush current, is not sensed as the flicker.

The polymerizable monomer is a radical-polymerizable monomer and is, e.g. a styrene monomer such as styrene. The hydrogenated terpene resin is added by 3-30wt.%, preferably 5-20wt.% of the amt. of the polymerizable monomer. In the case of <3wt.%, low-temp. fixability is not well satisfied. In the case of >30wt.%, it becomes difficult to regulate the resultant toner to have a small particle diameter.

Title: Wheel
Inventor: MORI KANJI
IPC: B60C13/00
Filed: 1994-09-16
Abstract: PURPOSE: To reduce the sudden abrasion of a tire caused by the landing of an aircraft to save enormous expenses by previously turning a wheel by wind force when the aircraft grounds. CONSTITUTION: To save expenses such as those of wheel replacement, the abrasion of a tire due to sudden rotation can be reduced by turning a wheel from slightly before starting the grounding of the wheel. Therefore, rotary bodies 1 rotated by wind force are attached to the inner sides of the wheels to be integrated with the wheels. When the wheel equipped with the rotary body 1 is lowered from the inside of an aircraft at the time of landing, the wheel receiving wind starts turning, the wheel is thereby turned already at the time of landing. Consequently, sudden abrasion is eliminated to reduce the frequency of the replacement of the tire, thereby saving expenses needed for the replacement.
